ci: update package lockfile and docs with changesets release

[zimeg]

Summary

• Adds a version script that runs changeset version, npm install, and npm run docs so the release PR automatically includes lockfile and documentation updates
• Updates the release workflow to use the new version script
• Removes manual npm install / npm run docs instructions from the maintainers guide

Notes

This mirrors the release process found in bolt-js: slackapi/bolt-js#2882

Requirements

• I've read and understood the Contributing Guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.

🪬 A note of these scripts combined-

[zimeg]

📣 note: We prefer this script alongside releasing in CI such that:

$ npm run version

• Updates the CHANGELOG.md
• Updates the lockfile
• Updates the generated reference

[zimeg]

🏁 Will merge this to match downstream projects processes! I'm most curious how generated reference appears alongside changes to dependencies in upcoming PRs.
